The Xbee Explorer Stick from RoboCore has the minimum needed to interface a Xbee module with your computer. It is compatible with all Xbees modules and uses the FTDI chip FT231XS to convert from USB to serial. It has on board voltage regulator, so USB voltage will not damage your 3V3 Xbee, also has a few LEDs to show its status (Power, RSSI, Rx and Tx). Thinking about protection, this module has a fuse, so there is no change of damage. Documentation: Schematic: https://s3-sa-east-1.aws.com/robocore-lojavirtual/731/XBee.Explorer.Stick_v1.0.pdf
